Deflector



, Patented June 24, ease UNITED STAA res PATENT OFFICE L'UDWIG BATTEBMANN, OI ROCKY POINT, NEW YORK, ASSIGNOB TO RADIO COR- PORA'IION OI AMERICA, A CORPORATION OF DELAWARE I DEIILECTOR Application mm June 15,

This invention relates to a deflector and is an improvement over the deflector disclosed by James L. Finch in his patent application Serial Number 370,813,'filed in the'United States Patent Ofiice June 14, 1929.

In the patent a plication referred to there is disclosed a de ector for usein connection with an ink jet recorder wherein a stream of ink, wobbled in accordance with signal 1 characters, traces the characters upon a mov-' ing tape. The deflector provided in the application referred to is centrifugally actuated by the movement of the tape and prevents spattering of ink over the tape when the driving apparatus therefore ceases to operate,'or, .to prevent spattering of the ink over the supporting means for the tape when the tapeterminates.

However, it is desirable to run the ink recorder of the general character referred to, at extremely high speeds, and accordingly, at those speeds, a centrifugally actuated deflector of the type disclosed in the application referred to would tend to burst. There'- fore, an object of this invention is to provide a centrifugally actuated deflector wherein above a predetermined speed, the tape driving it has no further effect upon the elements centrifugally moving the deflector out of the 3 marking stream, which may be as indicated of ink, or which may be of radiant energy utilized'to trace characters upon a sensitized moving record.

The invention may best be understood by referring to the accompanying drawing in which I have disclosed in Figure 1 apparatus for carrying out my invention; and in Figure 2 I have illustrated means for varying the speed ratio of the tape and the centrifugal control elements.

Numeral 2 indicates a stream source, here, afine bore jet spraying a stream of ink or other marking fluid 4 upon a moving record or tape 6. By means of electrodes 8 the stream 4 is wobbled according to desired signails and hence signal characters are traced upon tape 6. As shown, the tape for some reason say, breakdown of its driving apparatus, is stationary, and hence, baflie 1O intercepts the stream 4 causing it to flow through causing governor balls 32 to fly out and there- 1929. eel-m1 N0. 871,247.

a hole or channel in the bottom thereof as at 12 into a pan or other collecting device 14 to be subsequently repumped through jet 2.

Upon movement of the tape 6, the tape at 6 frlctionally drives a circular base memher Extending through the base member 1s a shaft 18 supported by bearings 20, and upon which are slidably and rotatably mounted discs 22, 24 having hub portions 26, 28 respectively. Attached to hubs 26, 28 are governor springs 30 to which in turn are attached governor balls 32.

As already indicated when the tape 6 is not movlng baflle 10 intercepts stream 4. I he bafiie is held in the intercepting posit on by means of spring'34 acting through links 36, 38, 40, to the latter of which bafile 10 is fastened. At the righthand end of link 36 there is rigidly fastened thereto a contact actuating element in the form of a circular ring 42.

Accordingly, when tape 6 starts to move, member 16 is rotated, thereby frictionally rotating disc 22 which rests thereon, thereby by causing disc 24 to press upon actuating element 42 raising lever 36, at its left hand end against the tension of spring 34, which, through linkwork 38, 40 causes baflle 10 to be removed from stream 4 allowing the stream to impinge upon the tape at 6, outlining signal characters thereon. However, before tape 6 moves at its maximum speed, which, if allowed to act upon disc 22 would cause the governor balls 32'to breakaway from the remaining structure, disc 24 contacts with stop 44, whereby additional rotative speed of 22 causing balls 32 to fly out a little further, raises disc 22 from frictional drive engagement with driving member 16. When 22 is raised from member 16 the governor slows down until disc 22 again contacts with member 16 whereupon,

by centrifugal action, balls 32 again raise' disc 22 from frictional drive engagement with member 16.

In this manner at maximum tape speeds governor balls 32 rotate at speeds causing alternate frictional engagement and disengagement of disc 22 with member 16, thereby preventing the bursting of the governor structure. v

In connection with this, as shown in- Figjurc 2, the gear or speed ratio between the governor and tape can be changed as desired. Here the tape at 6" drives member 16' through collar 50 and shaft 52. By means of set screw 54, member 16 may be made to drive governor disc 22 at any desired speed, by moving 16' radially along disc 22. A

Having thus described my invention what I claim is:

1; In a recorder, a travelling tape, a stream for outlining signal characters thereon, a baflle, means for moving said baflle into said stream thereby preventing said stream from outlining signal characters on the tape, means responsive to the speed of the tape for moving said bafiie out of said stream, thereby allowin the stream to outline signal characters on the tape, and means for preventing additional movement of the baflle out of the stream when said tape reaches a predetermined speed.

2. In a recorder a tape, means whereby said tape drives a device having a centrifugally actuated element thereon, a bafile, means for controlling the movement of the baflle according to the movement of said element, and means for preventin further movement of the .element at spee of tape over a predetermined value. 1

3. In combination a tape, a governor, an ink jet and a baflle, means for driving the governor up to and not over a predetermined speed, and means actuated by said governor when it reaches a predetermined speed for moving the baflle relative to the ink et.

4. In a recorder, means for directing an ink jet upon a moving ta a governor actuated by the movement 0 the tape at speeds below a predetermined value, a baflle, and means controlled b said governor for moving said baflle out o the path of said jet when said tape moves at a predetermined speed, and means for moving said baflle in the path of the jet when said tape travels below a predetermined speed.

5. In a recorder a travelling tape, a jet for causing a stream of fluid to mpinge. upon said tape, a governor, means for frictionally driving said governor by said tape solely at tape speeds below a predetermined value, a disc associated with said overnor, a baflle, means for causing said ba e to move into the
